In my post #17 it explains how to do the update from different versions of firmware. The attachment is instructions on how to update firmware. The section that tells you how to update firmware onto your remote controller starts at # 14. It will show you the steps to take to do the necessary updates. On older versions of firmware,you have to start the update process by means of a mini sd card with a usb card reader or a thumb drive ( usb flash drive)!
